FAQ:

Q: Can you plug RJ-11 into RJ-45?

A: Many analogue phones, however, are fitted with an RJ11 connector. These are smaller and have four pins. It’s easy to insert an RJ11 plug into an RJ45 socket and it will probably work for a voice connection if the other end of the link has the right wiring or the correct adapter.

Q: What is the different between RJ11 and RJ45?

A: The main difference between these two is in where they are actually used. RJ45 jacks are used in networking, where you connect computers or other network elements to each other. RJ11 is the cable connector that is being used in telephone sets.

Q: How many wires are used in RJ45?

A: RJ45 cables have 8 color-coded wires, and the plugs have 8 pins and conductors. Eight wires are used as 4 pairs, each representing positive and negative polarity.

Q: Is a RJ11 jack and a RJ45 socket physically compatible?

A: RJ11 and RJ45 connectors are not compatible nor interoperable because of the reasons explained above. The combination RJ11 plug – RJ45 jack is not expected to work properly. It may even damage the connector. RJ11 plugs should be used with RJ11 jacks, RJ45 plugs are to be used with RJ45 jacks.
